IMPROVEMENT IN sTRAw-cpuT-rsnps.

Specification forming part of Letters PatentNo. 193.189,v dateds-Jnly 17, 1877; application filed February 17, 1877.

To all whom it may concern Beit known that we, CHARLES SILBERZAHN and HERMAN HAYSSEN, of Sheboygan, in the county of Sheboygan and State of Wisconsin, have inventeda new and useful Improvement in Feed-Gutter, of Which the following is a specification. f

Figure l, Sheet l, is a side view of our imi proVed'feed-cutter, partly in section, through the line wa', Fig. 2. Fig. 2, Sheet l, is a top view of the same. Fig. 3, Sheet 2, is a front View of the same. Fig. 4, Sheet 2, is a reverse side view of the same, the ily -wheel being removed. Fig. 5, Sheet 2, is a detail longitudinal section of the same, the iiy-W-heel being removed. Fig. 6, Sheet 2, is a detail section ofthe fly-Wheel.

Similar letters of reference indicate corre- I sponding parts.

The object of this invention is to furnish a improved feed-cutter, Which shall be so constructed as to make the cut evenly and easily,

that will adjust itself to the thickness of the material being cut, and Will feed the material forward uniformly, Whether it be thin or thick, and which shall be simple in construction and convenient in use.

The invention Will first be described in connection with the drawing, and then pointed out in the claim.

A is the frame of the machine, to the top of which the feed-box B is attached, and Which is made with an L extension at its forward end, to prevent it from being lripped over or made unsteady by the Weight of the iiy-Wheel C. The fly-Wheel() is made With curved arms, and to two opposite arms are attached the knivesD. The knives D are made With a gradually-increasing curve from their outer to their inner ends, so that all parts of their edges may meet the bottom of the feed-box B',upon which the material lies to be cut at the same angle.

The knives D are bolted to lugs c', formed upon or attached to the arms of the ily-Wheel O, and their edges are adjusted to Work close to the end of the feed-box B by set-screws d', which pass through screw-holes in the lugs c', and rest against the said knives D. The forward end of the feed-box B is lined with steel to preventwear. The fly-Wheel C is attached to the forward end of the shaft E, which revolves in bearings attached to the L of theframe A and to the bracket F attached to said frame A.

To the shaft E, near its rear end, is attached abevel-gear Wheel, G, the teeth of which mesh into the teeth of the larger bevel-gear Wheel H attached tothe shaft I. The shaft I passes through beneath the feed-box B, revolves in bearings attached to the frame A, and has a crank,l J, attached to one'or both ends.

To the shaft I, near its other end, is attached a small gear- Wheel, K, the teeth of which mesh into the teeth of the larger gear-Wheel L. The gear-Wheel L revolves upon a spindle, M, the inner end of which is inserted in a curved slot in a casting, N, attached to the side of the. frame A, and is secured in place in said slotted casting N by-tightening up the nut that secures the gear-Wheel L upon saidI spindle. This enables the gear-Wheel L to be replaced by a larger or smaller gear-Wheel, as may be desired.

Upon the gear-Wheel L is formed, or with it is rigidly connected, a smaller gear-Wheel,

. O, the teeth of which mesh with the teeth of the larger gear-Wheel P attached to the journal of the lower feed-roller Q. The journals ofthe lower feed-roller Q revolve in bearings attached to the frame A, in such positions that the upper side of said roller may project through a transverse slot in the forward part of the bot-tom of the feed-box B.

To the end of the otherjournal ofthe feedroller Q is attached a small gear-Wheel, R, the teeth of which mesh into the teeth of a small intermediate gear-Wheel, Spivoted to the side ofthefeed-box B. The teeth of the intermediategear-Wheel S mesh into the teeth ofthe small gear-wheel T, attached to the end of the shaft V, which revolves in holes in the sides of the feedbox B, and to the center of which is attached a gear-wheel, V. The teeth of the gearfwheel V mesh into the teeth of the gear-wl1cel W formed upon the center of the upper feed-roller X, the journals of which revolve in vertical slots in the side-boards of the feed-box B. rlhe holes in the sides of the feed-boxB, in which the journals of the shaft U revolve, are made larger than "saidl journals.: and the vends of the said journals are counected with the journals of the upper feedroller X by bars or straps Y,and with the pivot of the intermediate wheel S. by bar or strap Z, and witha stud in corresponding position upon the other side of the 'feed-boi B by a similar bar or strap, Z. This arrangement keeps the gear-wheels V W and the gear-wheels R S T in gearwitheach, other as. the upper feed-roller X moves up and down to accommodate itself to the thickness of the material.

Withthe journals of the upper feed-roller X are connected the ends of the presser A', which holds the material in place while being cut, and 'at the same time coversA the upper l and forward sides of the upper feed-roller X,

The gear-wheels L Ov P are covered by a cap, B', -the gear R SvT'are covered by a cap, G', and the gear-wheels G H are covered with a cap, D', to prevent them lfrom being clogged, and to protect the operator fromv being accidentally injured by them.

To the top har of the of the frame e is attached a shield, E', to protect the operator from cominglin contact with the `knives D.

To the upper forward part kof the feed-bo1r the gear-wheel V, and prevent it from being clogged by the material.

With the journals of the upper feed-roller iX arefconnected the upper ends` of'vthestraps or bars H', the lower ends of whichlaref: connected with. the arms of the branched end of the leverI I". by linksom* short connecting-bars. The forward end of the lever I' is pivoted to the front barof the frame A, aud from its rear end is suspended ay Weight, J', to hold the upper. roller Xand the presser A" down upon the material with the necessary force.
